Here are results for the G-Power SKII CS supercharger kit results on an E92 M3 6-speed manual car from Bimmerboost vendor Precision Sport. The car dyno'd 502.6 wheel horsepower with the supercharger in SAE correction which is a substantial increase from the 339.3 wheel baseline. Keep in mind, the car has heavy 20 inch G-Power wheels which definitely affect the numbers. Regardless, the curve is very nice with a large increase in torque through the whole rev range.

Like I said originally the G-Power stuff is second to none in terms of quality & finish, but there are several other options that are less expensive & outperform it IMO. And if you're that bent on an air/air setup, Evolve & AA are alternatives.

Doesn't matter here in the US, but is the G-Power kit the only one with TuV approval (for the Euro crowd)?

@bobS, the gauge pod looks a lot like the Macht Schnell pod with different gauges. They def look a lot more clean without any manufacturer labels or anything.

The G-Power is an air/air setup. The kit makes comparable HP numbers as any other kit available, however our dyno runs are inclusive of the 20 inch G-Power wheels, which definitely lowers the HP numbers.

Since ASA and G-Power are owned under the same umbrella (Infinitas) they are able to develop the blower units from scratch to maximize the efficiency for each engine. For this reason, and the overall quality of the components, the kits are a little more costly than others.
